V 1 Claim.

This invention relates to supporting ledges for brick veneer and the object of the invention is to provide a ledge on a foundation wall which will extend outwardly and provide a support for a 5 brick veneer wall built on the ledge.

Another object of the invention is to provide a supporting ledge for brick veneer in which the ledge is keyed into a foundation wall at spaced intervals by means of reinforced concrete to provide a firm, solid support for the brick veneer wall.

Another object of the invention is to provide a means for holding the forms in place during the pouring of the concrete so that the resulting ledge extends longitudinally of the foundation Wall and is keyed into the wall at spaced intervals throughout its length.

A further object of the invention is to provide a connecting means for holding the forms in place and when the forms are removed the ends of the connecting means may be covered with concrete so that there are no exposed parts to rust or deteriorate.

These objects and the several novel features of the invention are hereinafter more fully described and claimed and the preferred form of construction by which these objects are attained is shown in the accompanying drawing in which Fig. 1 is an elevation of a wall with the forms in place for pouring the concrete for the ledge.

Fig. 2 is an enlarged section taken on line 2-2 of Fig. 1.

Fig. 3 is a section through the end of the connecting means after the forms have been removed.

Fig. 4 is an enlarged section taken on line 44 of Fig. 2.

Fig. 5 is an enlarged section showing the form in Fig. 4 removed and the recess pointed up.

Fig. 6 is a view showing an alternative form of connecting means between the concrete forms.

In building a brick veneer exterior on a frame building which is already built, it is necessary to provide some sort of a support for the brick wall at or near the grade line. For this reason, the earth is removed about the basement or foundation wall I to allow sufficient space in which to form the supporting ledge. The basement wall may be of concrete block and at intervals of about six or eight feet a portion of the concrete block is knocked out to provide space in which to key the ledge into the wall. This portion may amount to one-third or one-half of the usual concrete block as indicated in dotted lines in Fig. 1 and a plate 2 is positioned over the inside of the opening thus formed as shown in Fig. 2. This rre, Detroit, Mich.

plate 2 is provided with a pair of pins 3 which may rest on the bottom of the opening as shown in Fig. 2. The exterior wall form 4 extends longitudinally of the Wall with the top of the form at or near the grade line and this form 4 is provided with a sloping bottom portion 5. The form 4. is spaced from the wall I by means of adjustable spacers 5 which engage against the wall on opposite sides of the opening 1 shown in Fig. 2 and a reenforcing bar 8 is provided with threaded ends which extend through the plate 2 and form 4 and is provided with nuts 9 on the opposite ends thereof. By this arrangement the form 4 and plate 2 is held in place.

The plate 2 is provided with a series of socket members Ill riveted thereto as shown in Figs. 2 and 4 and reenforcing rods I l are seated in these sockets l0 and are supported at the opposite end by means of a wooden wedge i2 which is driven in between the opposite end of each rod H and the form 4. Longitudinal reenforcing rods l3 are then provided which extend longitudinally of the form 4 and rest on the transverse reenforcing bars H and are wired thereto as shown.

When thus assembled, the concrete is poured and this concrete will not only fill the longitudinal form 4 but will also fill the openings 1 which are spaced at six or eight foot intervals longitudinally of the Wall. After the concrete has been poured the wooden wedges l2 and spacers 6 are removed and the concrete is allowed to set. When the concrete has become hard, the nuts 9 may be turned up with a large wrench to break off the end of each rod which is provided with a slot I 2 to weaken the rod so that it will break under pressure exerted by the nuts 9. Due to the lugs on the reenforcing portion 8 of this rod, the rod is prevented from moving longitudinally in the concrete so that the tightening of the nuts will insure the breaking off of the ends of the rod 8. After this has been done the forms 2 and 4 may then be removed and the recesses at the ends of the rod 8 may be filled with concrete at l5, as shown in Fig. 3. Also in removing the form 2 the socket members I0 leave recesses in the wall which are filled with concrete at l6 shown in Fig. 5. By this arrangement none of the ends of the rods are exposed to weather and consequently the rods will not deteriorate when covered in the concrete.

When the ledge has thus been formed a concrete ledge is provided completely about the exterior of the basement or foundation wall I which is keyed at intervals into the foundation wall so that the wall itself will support the weight or load of the brick veneer wall which is built up on the exterior ledge thus formed. In brick veneer work, two inch brick I! may be used as shown in Fig. 2. In order to support the brick veneer wall, reenforcing rods l8 may be embedded in the reenforced concrete ledge at the bottom and may be secured to the siding or wood portion of the building at the upper end by the spikes l9. Tie wires 20 may be then fitted about the rod l8 and tied into the courses between the brick when the brick is laid. For the courses above the rods l8 the brick may be connected to the wood siding by ordinary sheet metal ties nailed to the wood siding.

In place of the rod 8, shown in Fig. 2, a rod l9 may be used which is shown in Fig. 6. In this I case, the rod I9 is provided with threaded recesses 20 for the screws 2| which extend through the forms 2 and 4 as shown. In this arrangement it willbe noted that the forms are spaced from the ends of the reenforcingrod I9 so that after the concrete has been poured and has set a wrench may be applied to remove the screws'Zl from the reenforcing'rod l9. This will allow removal of the forms and the openings left by the removal of the screws may be filled with concrete in the same manner as shown in Fig. 3.

From the foregoing description'it becomes evident that the device is very simple and eflicient atthe top, engage the wall at the bottom and extend longitudinally of the Wall over the apertures, an interior form adapted to cover each aperture on the interior side of the wall, the interior form being provided with a series of sockets adapted to support a series of transverse reinforcing rods, a bolt connecting the interior and exterior forms, the bolt being provided with threaded ends and being partially severed at a distance from each form, a nut threaded onto each" threaded end of the bolt and engaging the respective forms, the arrangement being such that as concrete is poured into the exterior form it will flow into and fill the wall apertures and when the concrete has set the nuts on the ends of the connecting bolt may be turned up to break the bolt where partially severed.
